Description

sensitivity is used to assess the impact of differing rho values on the correlated effects meta-regression model.

Usage

sensitivity(x)

Arguments

x

Examples

# Correlated Effects Model
CorrMod   <-  robu(formula = effectsize ~ followup + males + binge + college, 
                   data = corrdat, studynum = studyid, var.eff.size = var, 
                   rho = .8, modelweights = "CORR", small = FALSE)

sensitivity(CorrMod) # Output sensitivity
